Tracking Follower is a feature exclusive to primitive objects, video screens, and imported 3D objects. It allows you to visualize the location of environment trackers through the responsive movement of the chosen Viewport Object.
To apply the transformation of incoming tracking device data to a Viewport Object, all you have to do is follow three simple steps:
- 1.Place an Object onto the Viewport.
- 2.Select three different points from that Object.
- 3.Choose a Tracking Device.
In the Viewport window, choose a primitive object, video screen, or imported 3D object from the Toolbar and drag it to the desired spot on the Viewport floor.
To successfully apply the transformation on the Viewport Object, you first have to choose three different points on the Object itself.
Navigate to the Tracking follower section of the Properties window, and click on Add point button. Upon clicking, you will enter a special mode, indicated by the Pick a point label on the top left corner of the Viewport window. In this mode, the chosen Viewport object will be isolated and all other Viewport objects will become invisible.
If Render spheres checkbox is enabled, anytime you hover over the chosen object, a sphere will be drawn out. To add a point to the object, all you have to do is click on it.
Good to know: You can also exit the Pick a point mode without adding any points by pressing ESC key or left-clicking somewhere else in the Viewport.
In Tracker device dropdown menu you can choose one of the Device receiver nodes placed in the Devices window. After doing so, a new property called Tracker names will appear.
Here, you have to type the names of three trackers, as defined in the incoming data from the chosen Device receiver node.
